> Use Google Guava Intern Facility
> --------------------------------
>
> Key: TEZ-4275
> URL: https://issues.apache.org/jira/browse/TEZ-4275
> Project: Apache Tez
> Issue Type: Improvement
> Reporter: David Mollitor
> Assignee: David Mollitor
> Priority: Major
> Time Spent: 10m
> Remaining Estimate: 0h
>
> Google Guava has a pretty cool Interner facility.
>
> * More memory efficient than current offering. Map contains a weak key and
> a static dummy value (current implementation uses a weak value)
> * Current implementation has a single lock around the entire data structure.
> Google segments their data structure into (default: 4) segments for better
> concurrency
> * All the other thoughtful stuff Google has added into this feature
